Preparation for Group Activity 1 for all students.

Spend at least an hour, but not more than 2 hours to do the following before coming to class on Friday:

1. Research the chemical composition of the durable good or household good assigned to your group (it appears in the GroupList at the top of each group)

Some items have different parts, each composed of different materials, which may have different chemical compositions (for example a baby buggy could have “steel” framework with a particular chemical composition, rubber wheels with their chemical composition, and some fabric filling in the frame with its chemical composition; and you could list elements contained in each material).

2. Bring in 2 printed pages from your research (i.e., pages that are photocopies of something you found in the library or printed pages from a web search).  These will be turned in at the end of the activity with your name on them to show you did your homework preparation
